SPEOTAGLE TEMPLE AND METHOD OF MAKING SAME.

Application filed August 22, 1923.

My invention relates to spectacle temples, and has for its object to provide an improved spectacle temple that will ride easily on the ears of the wearer without irritating, in any way, the skin behind the ears. My invention further contemplates an improved method of making spectacle temples, the practice of which results in an extremely durable temple which will not show deterioration when subjected to hard usage.

I am aware that spectable temples have been heretofore constructed in such a manner as to afford considerable flexibility and ease of wearing, as compared with ordinary plain wire temples, the usual way of accomplishing this result being obtained by w ndlng a number of layers of pliable wires 1n spiral form around the temple wire. It has also been proposed to cover the temple wire with non-metallic material havinga smooth finish, thereby providing a temple of increaseddiameter, so as to have a relatively broad'bearing around the ears of the wearer. I have found thatwhile the wound wire temples possess considerable flexibility, the

separate strands of Wire are llable-to irritate the ears of the wearer whereas temples formed by covering the wire with a non-metallic mat rial, do not possess sufiicient flexibilitv, although presenting a relatively broad and smooth bearing surface to the ears of the wearer.

According to a feature of the present Invention, I propose to provide an improved temple and a method of making same, which results in temple having both the flexibility and durability of a wound wire temple, and the smooth wearing qualities of a non-metallic temple.

The above and other advantageous features of my invention will hereinafter more fully appear, reference being had to the accompanying drawings in which,

Fig. 1 is a View inside elevation of a co mplete temple constructed in accordance with my invention.

V Fig. 2 is a View in side elevation of the wire core embodied in the temple shown in Fig. 1.

Fig. 3 is a View showing a length of nonmetallic tubinu' prior to its applicationto the temple .core shown in Fig. 2.

Serial No. 658,753.

Fig l is a view similar to Fig. 1, showing a modified form of a completed temple.

Fig. 0 1s a view snrnlar to Fig. 2, showing the wire core embodied in the temple of Fig el.

Fig. 6 is a View similar to Fig. 1. showin a further modification in the form of a com pleted temple.

Like reference characters refer to like parts in the diflerent figures.

Referring to Fig. 2, the temple core 1 is preferably in the form of a number of flexible wires 2 spirally wound on a wire 3, the wires 2 being soldered, or otherwise secured, to the wire 3 at its ends, so as to form substantially a one piece core. The core thus produced is extremely flexible and durable and presents a relatively rough corrugated surface, as compared to a plain wire core. lV hile I have shown the temple core 1 as being composed of spirally wound wire, my invention also contemplates the employment of a plain wire core having its surface scored, or otherwise roughened, to presentsubstantially the same appearance as the core shown in Fig. 2.

In carrying out my invention I employ a tube 4 of flexible non-metallic material having a smooth finish, such as zylonite, bakelite, or other similar composition readily moldableand of a durable nature, a length of this tubing being shown in Fig. 3. The tube has a continuous cut 5 extending c0n1- pletely through the wall thereof into its hollow center portion, the cut 5 being in helical form. The cut 5 is made over only a portion of the tube 4:, leaving uncut portions 6 and 7 at the ends thereof. The core 1 is then inserted into the tube 4, until one end nearly reaches the end of the uncut portion 6. The other end of the core 1 then projects beyond the portion v7 of the tube just enough to permit the attachment. of the templeto the spectacle frame or lens. The tube 4 is then compressed along its entire length, with or without the simultaneous application of heat, as desired, the material of the tube 4 being of such a nature that it readily adapts itself to the form of the core 1, with the corrugations of the latter embedded in theinner surface of the tube. The tube 4 is thus permanently attached to the temple core 1 throughoutits entire length. If desired, asuitable cement may be applied either to the core 1 or to the tube l, prior to the pressing operation.

The completed temple then appears as shown in Fig. 1, from which it is apparent that it is then a substantially unitary member, possessing extreme flexibility,owing to the flexible nature of the core 1, and the existence of the helical cut 5 in the tube l. At the same time, my improved-temple presents a non-irritating bearing surface to the ears of the wearer, owing to the smoothnatureof the material of which the tube a is composed. '"A modification of my temple is shown'in Figs. 4 and 5, in which the temple core 8 is corrugated for only a portion of its length, the remainder thereof being flattened out, as indicated at 9. A non-metallic, cut tube 10, similar inform to the tube at extends around the corrugated portion of the wire core 8, terminating at the beginning of the flattened-out portion 9. The tube 10 is provided with a helical cut 11,- and is secured to the temple core 8 by being compressed thereon over the corrugatedportion in substantially the same manner as the tube 4.

' The'fiattened-out portion 9 of the temple core 8 provides stiffness in a vertical direction where it is desirable, and, atthe same time, provides flexibility in a horizontal direction, which flexibility is necessary in relieving the spectacle frame of strain caused by bending the temples horizontally when adjusting the spectacles on the wearer.

still further modification is shown in Fig. 6, in which the temple 'core employed'is substantially the same asthe temple core 8, shown in Fig. 5, whereas the non-metallic 1 tube 12 extends" substantially over the whole length of the core. The tube 12 is provided with a helical-cut 13 extending over the corrugated portion of the core, and its uncut 7 portion 14: covers-the flattened-out portion of v are produced the core. The tube 12 is compressed over its entire length to cause the corrugations of the core to beimb'eddcd therein, and to cause it tic-conform to the flattened-out portion.

From the foregoing it is apparent that by my invention I have provided an improved spectacle temple and a method of making the same, by the practice of which temples having a maximum degree of flexibility and durability, in addition to presenting a smooth, non-metallic bearing surface of relatively large diameter.
